to warn and protect employees from hazards which could cause injury due to electric shock, burns or failure of electric equipment parts. OSHA believes that this information, along with the training requirements for qualified persons, will provide employees the necessary information to protect themselves from arc-flash hazards.Īdditionally, in §1910.335(b), OSHA requires employers to use alerting techniques (safety signs and tags, barricades, and attendants). However, paragraph (e) of §1910.303 requires employers to mark electrical equipment with descriptive markings, including the equipment's voltage, current, wattage, or other ratings as necessary. A requirement to mark equipment with flash hazard warnings was not included in the 1981 Subpart S revision. Reply: OSHA has no specific requirement for such marking.

Question 1: When work must be performed on energized electric equipment that is capable of exposing employees to arc-flash hazards, does OSHA require the marking of the electric equipment to warn qualified persons of potential electric arc-flash hazards - i.e., as required by NFPA 70E-2004? 1 We apologize for the delay in our response. Your questions have been restated below for clarity. Thank you for your e-mail to the Occupational Safety and Health Administration's (OSHA's) Directorate of Enforcement Programs (DEP) for an interpretation regarding OSHA's requirements and the National Fire Protection Association's (NFPA) 70E-2004, Standard for Electrical Safety in the Workplace.
